Dataview Gets Int, Display Value From Another Table?
Jun 5, 2011
I have a form which is primarily pulled from Table1. Table1.fieldA is an integer representing a project phase. In the current Access display the form displays not the integer, but a String stored in Table2 that holds integer/String pairs representing all the phases.I'm trying to figure out the best way to reproduce this in my .NET formview. I could write code that would parse the int and display text, then reverse the process at save or insert, however then the code has to be updated if a new phase is added to the database. draw the String values from Table2 while preserving the binding to Table1 but I haven't figured out how.
I have a sqlDataSource that runs a stored procedure that returns a table of the days of the month that was passed in as a parameter, arranged as they would in a calendar. It also returns a second table which contains the event details associated with certain days of the month.Basically, how would I go about accessing the values contained in the 2nd table that is returned by my query?I have tried putting the result of the .select in a dataset, unfortunately I get a cast error. If I try to put it in a dataview, I only get the first table.[code]
I have a dataset that holds a few tables; Songs, Artists and SongArtists (relations between songs and artists). I want to bind a grid to a view of the songs so they are filtered by artist. A combo will provides the artistID. Is there a way to use a dataview.RowFilter to filter based on a table that the dataview is not "viewing"? Or is there a better way to do this type of thing?
I create a DataView that load a table from database.
Dim da As OleDb.OleDbDataAdapter da = New OleDb.OleDbDataAdapter("select * from customers order by name", cnmain) ' I load complete table
[Code].....
�Thst's all I need? Because when I recover the first row of DataView filtered, it appears the first row initially loaded when I don't put filter.. �Do I need to refresh DataView to view te changes?
I have populated a dataset from a text file and I can display it in a dataview. Can I and if so how do I, select a sub set from this dataset and display it in the dataview?
I have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** " Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1" Dim da1 As New SqlDataAdapter(strSql1, strConn)
For my app users can enter a SELECT statement themselves. This can be any select statement at all, it will be mainly used for creating a quick view e.g. SELECT * from table1 LEFT OUTER JOIN table2 on table1.id = table2.id.
Whatever this select statement maybe I load it into a datatable (after checking for no nasty stuff of course) in vb.net. I want to know the table names so I can query the database again for validation purposes on things like datatypes etc.
da.SelectCommand = New SqlCommand(sqlStatement, tempDB.Connection) da.MissingSchemaAction = MissingSchemaAction.AddWithKey dt = New DataTable da.Fill(dt)

If want to do a DataView.Find on a DataTable that is already 'ORDERED' by the Column I am seaching, so a DataView.SORT should not be necessary, but it throws an Exception if I don't give a .sort command before the .find command. Is there any way to avoid this apparant duplication ? and speed up the search time. Its a very large table - 1 million rows. I am using VB 2010

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.
